Top weekend show: Deadmau5 at Aragon

Deadmau5: Toronto DJ Joel Thomas Zimmerman’s headlining set at Lollapalooza last August offered further confirmation of his ascent to the top of the electronic-music ranks. If nothing else, the outfits his fans wear should be impressive – be prepared for an invasion of oversized rodents, 8 p.m. Saturday and 5 p.m. Sunday at the Aragon Ballroom, 1106 W. Lawrence, $50; ticketmaster.com.
